okey thank you, just need confirmation about combination fan for 36mm top. now i can use 59mm GPU back plate without sacrifice cpu cooling.Hi,
1. You can only install at bottom, you can either leave it at bottom or flip it around so the radiator will be at top.
2. Yes, a mix use of 25mm 15mm or 12mm fan will give you more flexibility to install thicker radiator.
